Also, what an interesting period between about 8 and 8.30pm when the temperature seemed to rise from c26C to 30C.

The sea breeze then dies as a front approaches from the west into the evening, with the wind veering SW'ly. This destroys the low-layer cooler/humid conditions and returns us to hot continental.
That then cools into the night.
It was a remarkable afternoon. I spent it in Sittingbourne, at work, a few miles away.

The cooler sea air didn't make it that far inland until the evening - and it was a scorching afternoon as a result. You can see the same dewpoint rise / temperature fall as I had at home, just more muted. It even has the small rise as the layer was destroyed.
The sea breeze at home saved my server in the back bedroom from overheating - it "only" reached about 38C indoors, whereas without the cooler air and the wind it would have gone well into the 40s.
At work - I went to the airconditioned luxury of the Holiday Inn down the road. It meant it cost me to go to work that day, but that hotel was worth every penny. It was 19C in my room there, whereas at home it would have been too warm to even use the portable a/c - they conk out at 35C!
